Digital Radio Mondiale - DRM30 and DRM+

The DRM standard

DRM, Digital Radio Mondiale, is a digital radio standard, approved by the DRM consortium in 1998. The consortium developed this digital transmission system for the AM-bands, i.e. for long-, medium- and short waves up to 30 MHz (DRM30) and launched this system worldwide. The extension of the DRM system family to upper frequency bands up to 174 MHz (DRM+) is standardized under ETSI ES 201980 V3.1.1 (2009-02-16).
